Discards outbuildings (5)
I believe the answer is:
sheds
This clue is a double definition.
'discards' is the first definition.
(I've seen this in another clue)
'outbuildings' is the second definition.
(shed is a kind of outbuilding)
(Other definitions for sheds that I've seen before include "Casts off the outbuildings" , "stores" , "Discards" , "Single-storey outbuildings" , "Gets rid" .)
